Engine design changes

In the "it sounds like a great idea" category, a recent article in Trucking Times (www.truckingtimes.com) included some info about GM's future engine development.

Using GM's supercomputers, engineers worked on a new design — measuring such things as heat, flow and stress on screen. The engine's design reverses the flow of air and exhaust gases going in and out of the cylinder heads.
On standard V-8 engines, fuel and air enter on the side of the cylinder heads facing the inner part of the "V." The exhaust gases exit on the V's outside. In the new design, air enters the engine through ports in the outer portion of each cylinder head. The exhaust gases then exit inward between the cylinder heads and directly into a turbocharger.

I saw an old air cooled v-12 tank engine that was set up that way.
